Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed February '16, 1915. Serial No. 8,564.

a still of simple structure adapted when in operation to efliciently and quickly convert crude oil into vapor or gas whereby the solid matter or residuum may be easily separated from the same. i

With the above objects in View the still includes a walled structure having heat inlet and heat outlet openings. Headers are supported in the walls of the structure and are connected by pipes which are arranged in inclined positions. The said pipes are arranged in sets and partitions are located between the sets and constitute baffle walls for the purpose of properly directing the heated gases along the pipes as it passes along the same. Means is provided for admitting crude oil into the lowermost header and means is provided for permitting the vapor and residuum to escape from the uppermost header of the series of headers.

In the drawings :--Figure 1 is a vertical longitudinal sectional view of the still. Fig. 2 is an enlarged detail sectional view through one of the headers of the still. Fig. 3 is a side elevational view of one of the headers. Y

The still comprises a wall structure 1 having headers 11 located in the opposite walls thereof. A pipe 3 is connected with the uppermost header lland a pipe 4 is connected with the lowermost header of theseries of headers. 4

The structure 1 is provided in one of its walls with a heat inlet opening 9 through structure 1. The headers at one of the walls H headers 11 are inwardly occurring opposite the closed portions of the intermediate portions as at 2 wherebythe inner surfaces of the said headers lie in planes at an angle to each other. These an-' gularly disposed surfaces of the headers at one side wall of the structure are parallel with portions of the inner surfaces of the headers at the opposite side of the structure. Pipes 12 connect the headers at the opposite sides of the structure 1 together. These pipes are arranged in inclined positions as shown in Fig. 1 of the drawing and communicate with the headers at the opposite walls of the structure at their opposite ends atthe inner surfaces of the headers which are parallel with respect to each other. The pipes 12 of each set of pipes are parallel and each set of pipes is inclined in an opposite direction from the'next adjacent set of pipes.

As will be seen in Fig. 2 of the drawing each 0f the -intermediate headers 11 comrises two angularly disposed sections which Join with each other and one set of pipes 12 connects with one section while the adjacent set of pipes 12 connects with the other section of the header.

Partitions 13 of fire brick or other suitable material are located over each set of pipes 13 and constitute baffle walls which cause the heated gases entering through the'openrng 9 to pass in a zigzag path through the still. Consequently the oil which is in the pipes 12 is subjected to a blast of'heated gas and this has the effect of separating thevapor 1n the oil from the heavier particles.

The crude oil is led into the lowermost header 11 through the pipe 4 and the said I oil passes up through the pipes 12 and enters all of the'other headers 11 in the structure 1. During theupward movement of the oil thelighter particles thereof-are vaporized. The vaporized oil and the residuum is taken from the still through the pipe 3. After the vaporized oil and the heavier particles have been. conducted from the still they are separated from eachother in any suitable manner by passing the said materials through a separator and finally condensing the vaporized oil into liquid form. Therefore it will be seen that a still of simple structure is provided and that when in operation the heavier particles of oil as they are passed through the still are subjected to the most lntense heat and consequently 'the'process of convertiing the oil into vapor is materially facilitate Having described the invention what is claimed 1s A still comprising a walled inclosure having a heat inlet and a heat outlet, headers located in the walls of the inclosure, pipes connecting the headers at the opposite sides of the inclosure together, said pipes being arranged in sets the pipes of one set being inclined at an angle with relation to the pipes of the next adjacent sets, bafiie walls located upon the uppermost pipes of the sets of pipes and dividing the inclosure into heating chambers superim osed one above the other, the adjacent be e Walls converging toward each other whereby the said heating chambers are rendered smaller at one end than at the other, there being spaces provided between the ends of the bafiie walls and the walls of the inclosure at the upper sides of the said heating chambers and at the smaller ends thereof whereby the heat may ascend from. the smaller end of one chamber into the larger end of the chamber next above, the admission ends of the said chambers being of greater transverse sectional area than the exit ends thereof, means.
